T0 all whmn it may concern:

Be it known that we, CHARLEs F. GRIMM and Burns FULLnRToN,citizens of the United States, residin g at Oakesdale, in the county of Whitman and State of Washington, have invented a new and useful Onltivator, of which the following is a specification.

This invention relates to cultivators, andl has for its object to provide an improved designed to scrape the surface of the ground for the purpose of destroying the spontaneous growth which springsup after summer fallowing. It is f urthermore designed to provide an improved connection between the scraper-blades and the frame of the device, and also to provide an improved draft connection, so that t-he height of the draft may be conveniently adjusted to Vary the inclination of the action of the scraper-blades.

With these and other objects in View the present inventon consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departingfrom the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure lA is a perspective view of a cultivator constructed and arr'anged in accordance with the present 'invention Fig. 2 is a top plan view thereof. Fig. 3 is a transverse sectional View taken on the line 33ofFig.2. M

Oorresponding parts in the several figures of the drawings are designated by like characters of reference. i

Referring to the accompanyin g drawings, 1 designates a straight angle-beamwhich forms the frame of the cultivator and to which are connected the scraper-blades 2, the opposite draft connections 3, and the driveris seat 4. This angle-beam is arranged with one side 5 in a substantially-horizontal position and projecting rearwardly from the under edge of the opposite upstanding side thereof, and bolted or otherwise secured to the upper face of the rearwardly-extending side of the framebeam is a plurality of angle-plates 6, which |frame-beam by means of suitable fastenings `9. Thus these angle-plates are secured -to both sides or sections of the angle-frame beam and also project a'suitable distance in frear thereof.

Vice of this character which is especially de- Each an gle-plate is provided with a scraperblade'2, which is formed from a single plate |that is bent intermediate of its ends, so as to form ashank 10, which inclines upwardly and rforwardly in a Vertical plane, while the blade proper is in a substantially-horizontal plane to scrape the surface of the ground. Each shank is fitted flat against the outer face of the upstanding side of the respective angieplate and. is secured thereto by means of a clamp-strap 11,'thatembraces the outer side of the shank and is secured at its opposite ends to the angle-plate by means of, removable fastenings 12, which are located beyond the opposite front and rear edges of the shank. By this arrangement the shanks are not weak- 4ened by perforations for the reception of fastenings, and Athe draft upon the blades will draw the frontand rear edgesof the shanks against the respective fastenings 12, and thereby prevent loss of the blades.

Also the blades may be readily and conveniently replaced when worn or broken.

As best illustrated in Fig. 2, it will be seen that the blades are arranged in two groups,

of each group being inclined rearwardly and outwardly toward its respective side,and the adjacent blades overlap, so as to effectually scrape the ground and destroy the vegetation. The groups of blades are separated bya central intermediate vspace in which are located a pair of angle-plates 13 and 14, which are longer than the similar plates 6 and have their upstanding sides or fianges located upon the inner sides of the plates, and thereby adone at each side l'of-the cultivator, the blades jacent to each other, so as to form clamps for the shanks or stems 16 of the pair of central blades 17, each of which belongs to one of the groups of blades. These plates 13 and 14 are secured to the frame-beam in the manner described for the other similar plates, but are somewhat longer and have their adjacent IOO sides connected by removable fastenings 18 to clamp upon the shanks of the central blades. In rear of the shanks 16 and secured rigidly to the respective angle-plates 13 and 14 are suitable blocks 19 to form a broad bearing or base for the attachment of the seatstandard 20, which has its lower end bent rearwardly, so as to form a foot 21, which is secured to the blocks and the angle-plates in any suitable manner, whereby the Weight of the driver is located substantially midway between the front and rear edges of the cultivator and at the forward ends of the blades.

The draft connections for the cultivator comprise the opposite bars 22, which have pendent ianges 23 at their rear ends, said flanges being fitted against the enter side of the angle-beam 1 and provided with a plurality of vertically-disposed perforations for the reception of a bolt 24, whereby the draftbars may be adj usted vertically upon the cultivator-frame, so as to vary the inclination of the action of the scraper-blades, as will be understood. The forward end of each draftbar inclines downwardly, so as to form an angnlar bar, and is provided at its outer end with an npstanding transverse fiange or shoulder 25, to which is connected an eyebolt 26 for connection with the dra-ft-animals. Each draft bar is braced and strengthened by means of a flat bar 27, which has its outer end provided with an upstanding fiange 28, fitting snugly against the similar fiange of the draft-bar and receiving the eyebelt. The rear portion of this hrace-bar extcnds in rear of the draft-bar, and the latter is provided with a terminal flange 29, that is secured to the upper face of the brace-bar.

Vhat is claimed is-- 1. In a cultivator, a frame comprising a transversc angle-beam, having one side eX- tending rearwardly in substantially a horizontal plane from the opposite side thereof, :mgle-plates having their horizontal sides connected to the horizontal side of the framebeam, and their opposite upstanding sidcs provided with inner lateral flanges that are secured to the rear face of the upstanding side of the frame-beam, and pendent scraperblades secured to the respective angle-plates.

2. In a cultivator, a frame comprising a transverse an gle-beam, rearwardly-extending angle-plates, having their respective sides connected to the horizontal side of the framebeam, and their opposite upstanding sides provided with inner lateral flanges secured to the upstanding side of the frame-beam, scraper blades having upwardly and forwardly inclined shanks fitted fiat against the outer sides of the upstanding parts of the respective angle-plates, clamp-straps extending transversely across the respective shanks, and fastenings connecting the opposite ends of the straps to the angle-plates and clamping said straps upon the shanks.

3. In a cultivator, a frame, comprising a transverse an gle-beam, a pair of angle-plates, having their horizontal sides connected to the horizontal side of the frame-beam, the upstanding sides of the plates being arranged adjacent to each other, and provided With inner and oppositely-extending fianges secured to the upstanding side of the frame-beam, one or more scraper-blades, each blade having its shank located between the adjacent sides of the angle-plates, opposite fastenings connecting the adjacent sides of the plates and clamping the latter upon the shank, and a seat supported upon the rear ends of the plates.

4-. The combination with a cultivator, of a draft device, comprising a draft-bar, having a rear pendent fiange to fit against the frame of the cultivator, and provided with a plurality of vertically-disposed openings, a fastening for engagement With any of the openings and to verticaliy adj ustably secure the bar to the frame, the main portion of the bar being inclined downwardly and forwardly, and provided with a terminal upstanding flange, a brace-bar fitted to the under side of the draft-bar, connected to the lower end of the rear fiange, and having a front upstanding flangc snugly fitting the similar flange of the draft-bar, and an eyebolt extending through the combined fianges, and for connection with a draft-animal.

In testimony that we claim the foregoing as our own we have hereto afiixed our signatures in the presence of two witnesses.
